Asymptotics of spherical dynamos exhibiting a small-scale MAC balance
Justin A. Nicoski, Andy Esseln, Chris Davies +1
Understanding the asymptotic behaviour of numerical dynamo models is critical for extrapolating results to the physical conditions that characterise terrestrial planetary cores. He…
Accessing the dipole-multipole transition in rapidly rotating spherical shell dynamos
Andrew T. Clarke, Christopher J. Davies, Souvik Naskar +1
Polarity reversals are a key feature of Earth's magnetic field, yet the processes governing them are still poorly understood. Dipole reversals have been found in many numerical dyn…
Local Flow Estimation at the top of the Earth's Core using Physics Informed Neural Networks
Naomi Shakespeare-Rees, Philip W. Livermore, Christopher J. Davies +4
The Earth's main geomagnetic field arises from the constant motion of the fluid outer core. By assuming that the field changes are advection-dominated, the fluid motion at the core…
Force balances in spherical shell rotating convection
S. Naskar, C. J. Davies, J. E. Mound +1
Significant progress has been made in understanding planetary core dynamics using numerical models of rotating convection (RC) in spherical shell geometry. However, the behaviour o…
